CLOTHES WRINGER.

Application filed November 7, 1924. Serial No. 748,318.

This invention relates to clothes Wringers, and more particularly to an improved drive and safety device control-for wringers and the like class of apparatus.

An ob 'ect of the invention is to provide a device of the character described which may bereadily installed for household use or use in connection with washing machines and which includes practical operating control Other objects of this invention will in part- 'be obvious and in part hereinafter pointed out. i

Certain features herein shown andf'described are shown, described, and claimed in my Patent 1,538,993 granted May '26, 1925, and therefore are not claimed herein. The invention accordingly consists in the j features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter described and of which the scope of application will be indicated in the following claims. In the accompanying drawing, in which is shown one of the various possible illustrative embodiments of this invention,

Fig. 1 is a front elevational view, with parts brokenaway, showing the Wringer together with a motor for operating the same mounted as a unitary structure and installed on a wash tub for household use; Fig. 2 is a cross-sectional view taken on line 2--2 in Fig. l; Fig. 3 is a plan view of an'installation em- .bodying the invention; 1

Fig. 4 is a view similar to Fig. 1 but showing an interconnecting means for shutting 'ofi the power to the roll drive-simultaneously wi(tih the release of the roll tension control; Fig. 5 is a cross-sectional view taken on line 5-5 in Fig. '45 of the rolls and guard member. F'g. 6 is a plan view of the top of the wringer frame.

Referring in detail to the drawing, 10 is a wringer machine frame consisting of upright I standards 11,' 11' secured to the base 12 and a cross member 13 normally fastened to the upper ends of said standards 11, 11 as shown in Fig. 1. The standards 11, 11' carry the gear casings 14, 14 in which are housed the pairs of gears 15, 15f and 16, 16. The lower gears 15, 16 are supported on a horizontal shaft 17 which in turn is journaled in bearings 18, 18 in the standard 11, 11. The shaft 17 extends at one end 17 thereof into the 12 by any suitable means, such as the bolts 19. Supported above shaft 17 is the upper shaft 20 journaled in a pair of vertically movable bearing blocks 21, 21' mounted in the standards 11, 11'. The shafts'17 and 20 carry the usual wringer rolls 22, 23. Mounted on the front and rear sides of the gear castransm'issionbox 19 supported on the base ings 14 and 14 are brackets 24 and 24 which are adapted to removably support a guard member 25 therebetween. Said member 25 is provided with a slotted portion 25 to per-. mit feeding therethrough the clothes to be wrung, the flanged sides 25 of member 25 serving to prevent the accidental insertion of the operators'fingers'between the rolls 22 and Y 23. The bearing blocks 21, 21 are recessed as at 26, 26" to provide'seats for the lower ends of the tension springs 27, 27 The upper ends 28, 28 of these springs are disposed in similar inverted recessed portions 29, 29- formed in the presser blocks 30, 30, at the ends of the tension bar or cross memher 31. The presser blocks are preferably formed integral with-said tension bar. For tensioning the rolls 22, 23, pressure is applied to the tension bar 31 by means of" the hand wheel 32 having a threaded shank 32- (extend ing through a central opening 33 of the cross member 13.-

Power means is provided for rotating the rolls 22, 23 and for reversing the direction of rotation thereof when desired. To this end a reversing power drive is provided for one of the shafts, such as the lower shaft 17, comprising a pair of- 'beveled gears 34:, 34' mounted; in opposed relation to each other and. at righ an les to are as and inoperative relation -t ereto. latter is driven by the power shaft 39 which may beoperated by any suitable power means, as for example motor 40, and a sultable reduction gearing v 'which; may also be included in said power 36 is provided for throwing either one of the gears 34, 34' into mesh with the driving gear 35. This clutch is operated by a link member 37 pivoted to a horizontal arm 38 extending across the wringer beneath the rollers. This arm 38 is provided with an operating handle 38 and notches 38", 38, and 38 whereby the arm may be held inadjusted position, by selectively engaging said notches with a de tent member 50. (See Fig. 1.)

As will be clear from the drawing, when link member 37 is in position A, bevel gear 34 is in mesh and shaft 17 will be driven in one direction; and when the link is in the position shown at C, the bevel gear 34 will be in mesh and the shaft driven in the opposite direction. When the link is in the neutral position B, the shaft is at rest.

The means for separating the upper wringer roll 23 from the lower roll 22 will 'now be described. Straddling each end 13,

13 of the cross member 13 are the keepers 42, 42' preferably inverted U-shaped. The keepers 42, 42' extend downwardly over the cross member 13 and are pivotally secured as at 43,43 to the standards 11, 11. A hand lever 44 is provided which may be pivoted by means of a pin 44 to the cross member 13. Thishand lever carries a pair of link arms 45, 45 for connecting the keepers 42, 42 respectively thereto. The arm 45 is pivotally connected to the lower end of the lever 44, andis pivoted at the other end to the keeper 42. The .arm 45 is pivotally secured to the lever 44 above the pin 44 and at the other end tothe keeper 42.

The operation of the safety device for the separation of the rolls will now be clear. \Vhen the lever 44 is in inclined closed position, as shown in full lines in Fig. 1, the keepers 42, 42' straddle the crossmember 13, thus holding the tension bar 31 down with the presser blocks 30, 30' thereof compressing the springs 27, 27. The wringer rolls are then in operative position and under proper tension as previously adjusted by the hand wheel. If the operator should get a hand caught between the rolls, he quickly strikes the hand lever 44 throwing it into open position shown in dotted lines in Fig. 1. The link arms 45, 45 connected to the hand lever will then push outward on the keepers 42, 42 causing them to rotate out of 'holding position, thus releasing the presser bar 31 and cross member 13. The bearing blocks 21, 21 will then be released to permit upward movement of the shaft 20 with the roller 23 thus quickly freeing the hand. The rollsimay then be re-set for operation by turning the hand wheel 32 to release the tension, swinging the hand lever 44 down to simultaneously restore both the keepers to their effective-position, and then, readjusting the-tension appliedto the rolls by turning said wheel 32 as will be readily understood.

The wringer may be mounted in the form of a unitary device adapted for household use or .in combination with washing machines. In the former case base member 12 may be pivotally secured as at 49 adjacent one end of the rear wall of a wash tub 51, and mounted adjacent the pivoting point 49 is the motor 40 and transmission box 19'as already described. For clamping the wringer and motor accessories in position,

the free end 48 of the support 12 is provided with suitable clamping means, such as a spring catch comprising a shank 52 which extends through the support 48 and carries a spring 53 which normally urges a clamp member 54 in straddling holding position over the wall 55 of the tub. In this way, a complete unitary motor operated wringer is provided which may be easily swung-into and out of operative position and secured in place.

By the arrangement of the roller releasing lever 44 and drive control arm 38 on the same end of the wringer and within convenient reach of the operator, as shown in Fig. 1, practical and efficient means are provided to facilitate the safeguarding of the operator and the machinery, since the rollers 22, 23 may be easily and quickly stopped, reversed, and separated, selectively or concomittently as desired.

In Fig. 4 is shown a modified embodiment of the invention which includes means for interconnecting the wringer roller tension releasing control with the roller drive control. Said means comprises a pivoted releasing detent member 60, in place of the stationary member 50, shown in Fig. 1. Said member is connected in any suitable manner to the keeper 42, as b means of the link 61, the lower end of sai link being provided with an elongated slot '70 wherein projects a pin 71 mounted on said detent member to form a lost motion connection therebetween, as shown in Fig. 4. In order that the clutch may be returned to the off or non-driving position when the detent member 60 releases the arm 38, a pair of opposing springs 62 is provided, each spring having one end anchored on the transmission box 19 on opposite sides of link member 37, the other ends being secured to said member 37. j

vThe operation of the above described interconnected control means will now be apparent. With the lever 44 in effective tension position, thedetent member 60 is in raised position and the roll drive control may be operated in the usual manner by manipulation of the arm 38. On raising the lever 44 to release the tension on the wringer rolls, the detent member 60 is depressed, thus releasing the arm 38 and permitting the spring 62 to throw the clutch to ofi position. Thus the lever .44 controls the releasing of the rolls and simultaneously is effective to cut off the driving power.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved and which is well adapted to meet the conditions of practical use.
